Title: Diffusion state prediction method of diffusant
Inventor: OBA RYOJI
IPC: G06Q10/04
Filed: 2002-04-16
Abstract: <P>PROBLEM TO BE SOLVED: To determine by computing the concentration of a diffusant diffused in the air, and to smooth the change with time of the determined concentration similarly to the actual concentration change.  <P>SOLUTION: A material discharged from a discharge source S is replaced by particles, and the position of the particle is determined by operation. The particles are generated to the number of N/2 at each Δt/2 second. The position of the particle is operated at each Δt/2 in a region near the discharge source S, and the position of the particle is operated at each Δt in a region far from the discharge source S. Since the particle position is operated at short time intervals in the near region, the change with time of the determined concentration is smooth. Though the particle position is operated at long time intervals in the far region, the change with time of the determined concentration is smooth, because the particles are diffused widely. In addition, since the particle position is operated at long time intervals in the far region, the operation time is short as a whole.  <P>COPYRIGHT: (C)2004,JPO
